    Abstract: This article introduced the difference in the bus-transfer current switching requirements required by the disconnector in the double busbar substation. It calculated bus switching current and fracture voltage for the needs of the disconnector. It also provided suggestions for the current conversion capability of the disconnector.This work takes the 252 kV GIS disconnector as an example. It proves that the switch design for the speed improvement of the opening and closing is effective for the high-parameter bus-transfer current test.
    Key words: double busbar substation; disconnector; bus-transfer current
